By now, with your gentle prodding, I should know better.
The only thing I can think of was that I must have had a typo in my
ATLAS environment variable. I set it by hand in the command window each
time I recompile. The reason I do it that way is that I need ATLAS
*only* when compiling scipy, so I define it only when needed, rather
than have it cluttering up the space. Obviously, there is danger of
making a mistake this way. But I did learn something: atlas is not
needed for scipy_core. If I had figured that out, I would have figured
out my problem.
sorry about the noise,
